just a measure of the pixel density. Third, DPIndependent of the physical density of the unit of measurement, it is based on 160dpi , regardless of the DPI screen, 1DP represents the same physical length. In the 160dpi screen, 1DP=1px, that is, a DP needs to be represented by an PX , on the 240dpi screen, 1DP=1.5px, indicating a DP needs 1.5 px to indicate. That is to say 1DP=dpi/160*px. The implication is that developers will be able to develop a UI that displays the same size, regardless of t

The dip was used in earlier versions of Android, and the DP name was later recommended for unification with SP.Sp:Abstract pixels independent of scale (Scale-independent Pixel).

Difference between dip, dp, sp, pt and px in Android, androiddip 1. Overview In the past, programmers often designed computer user interfaces in pixels. For example, the image size is 80x32 pixels. The problem with this processing is that if you run the program on a new display with a dot (dpi) higher per inch, the user interface will look small. In some cases, the user interface may be small to difficult to see the content. Therefore, we can solve th
